They are big - own a number of major boards and then ca 35 micro boards - I think 40 in all. They appear to have a decent reputation and their main USP is that they link everything together for you. One of their microboards is jobsinsalesandmarketing. I have not, however, used them to recruit sales people so cannot specifically comment. They also have a board where employers advertise direct which might be of interest assuming this is what you are. Some people prefer to go direct to employers so this could be a bonus. [but a few other boards do the same, of course]

Hotonline list on HireScores.com but I only know the marketing people. They are certainly investing to make a success so this should be a good sign. I do not know if they do free trials. Talking of which how did you get on with jobsgroup.net who did offer a one day free trail?
